NEW Pro Boat Impluse 31 RTR V2

[dana]

It's mind boggling how companies put out stuff they claim is 6s compatable, with all the available knowledge in FE boating. We all know 1800kv is too much for 6s, yet that's what they put in there. Who is making these choices? Fire them.

[dana]

Even more mind boggling, is proboat has a 1500kv motor that is good for 6s, and they put the 1800 in there lol....
I just don't get it.

Hi dana,
I agree with you, but I think it's also a question of monopolies.
They (producers) can do everything they want, In some way you're forced to buy an RTR boat from them.
Otherwise, you have to buy the peaces and build it by yourself like in a static modelng.
This things makes me screaming!
Salute all, Niky.

100_0213.jpg100_0217.jpg100_0227.jpgImpulse 31 v2 Problems begin
servo does not work
esc does not work for high volt cutoff and cutoff type ldle, (can not be programmed with programming card)
program card will not work
sent back to Horizon
incredible disservice
after 10 day, proboat not have parts for warranty, out of stock

Disaster. Honestly, I like proboats hulls, but everything else on them are junk. I have never had proboat electronics that have worked correctly. Ok, the motors are ok too... But after having 3 proboats and nothing but issue after issue, I totally understand your frustration man

[Niky]

Hi Guys,
... and what about the Revolt 30 from Aquacraft?
I saw the videos, it's cornering with no problem at full throttle, incredible!
To put the 180A ESC+Leop.1600kv motor (upgraded parts for Spartan), on 6s I think it will run around 60 MPH.
I'm just thinking, but as idea it's not crasy at all.
Salute all, Niky.

[dana]

The problem is the revolt hull is gonna be tough to control at 60mph.its just not designed to do it. Don't get me wrong, you can get it to 60, but vs a good 60 mph hull, it doesn't stand a chance. The impulse hull would probably do better at 60 based on design.

[olwarbirds]

What I dont understand...is if PB knew (and they did) that there was an issue with running 6S in their new boats..why did they not change their ads....and let us know ..hey esc is 6S but the too little wired motor is only
4S...also the coupler on the new impulse is junk!!!...we sell these boats..I have both of them...I feel the pain others are feeling with buying the boats then buying lipos to do 6S, plus possibly a charger...I have a customer who has done all the above...what am I suppose to say to him...oooops some chinaman messed up, sorry about your luck !!!! The rep here on this forum has ignored my PM asking for some assistance, so guess its more hotair ...PB is trying to blow smoke at me, just like their motors smoke...Not gonna happen!!! Want to know why the USA hobby industry is in trouble...HH included...heres your sign...might as well buy direct from china ...same issues but with a lower $ price tag.....

Insane boats FE34 ....it can handle it....

[hobby_man]

I like my Revolt, I would not try to make it go 60, the hull is just too small

With ALL the thread information on this boat here on this particular forum, if you don't realize that you MUST reinforce the hatch to run this boat 15mph above it's RTR speeds and crash it there, then it's really on you. If you buy, bump up, and roll a Traxxas Stampede, and tear up the factory bodywork, is it still a POS???

I've gone to great lengths here to inform and SHOW you all what you need to do to ABUSE these boats... Whether you take the advice is up to you...

A simple addition of a layer of 6oz Fiberglass or Carbon cloth, laid up with some decent epoxy, on the underside of these hatches, is all that is required to prevent this.

Sorry that your RTR (low cost, fully assembled by 12-year-olds in China with average materials on a mass production basis) doesn't meet your lofty expectations. Perhaps one of these days, some company will offer a fully top-of-the-line RTR package for under $400.00. Until then, taking some steps to protect your investment might be well advised...

[Darin Jordan]

Now... that being said... I would also like to see these hatches built a little heavier, and have fed that info back to Pro Boat (last year...)... I'll try to make sure these things are better in the future, as I've been doing for 5+ years now...

THAT's the ticket!! :)

Thanks Darin, I try to improve every day
I visit Seattle in February, the home of my children
I will repair
improved stability with ESC front
thanks manny

[Darin Jordan]

improved stability with ESC front
thanks manny

Manny, when you say "improve stability", can you describe?? I might have some tips that would help... I know a few tricks for this boat that I haven't shared... yet...

[mannytx1]

HI Darin

more weight to the front
batteries more near the CG
Possible correction torque roll
improves cooling system
the antenna of the other side (cosmetic)

I have found that getting the weight too far forward causes issues... I've had better luck with having the weight at the CG, and then using the tabs to get the nose down. Keeps the ride back at the keel where it belongs...

A tip to ALL of you... Replace the turn fins with some squared/rectangular fins... For starters, you may just take a set like the Revolt's and modify them to fit. They don't have to be very long... My fins for the P-Ltd setup are about 1/4" above the keel when viewed from the back. Make sure they mount RIGHT up against the transom, and extend down at just a slight angle. Make them about 1.25" or so in chord. You will be AMAZED at the stability you'll suddenly realize, especially in the corners...

I sent a pattern to Steven and I believe that OSE may be working to produce/supply them for you. Future offerings from Pro Boat will also have this design. It's a "design flaw" that I put into this boat, and the one real "mistake" I think I made when developing it. The straight fins make the boat much, MUCH more drivable in the turns, especially when it gets rough. Try it!!

[mannytx1]

thanks Darin
please send me some pictures

ESC put forward, backward batteries, together CG is nearer

center of gravity that% to over 45mph???????? 30% o 31% o 32%

Tried a motor and esc swap....leopard 4082 2000kv 180amp esc....on 6S with stock prop ...at 2/3 throttle its running way to dry. Definately a lower KV for 6S is needed, my buddy never could open it up, it was uncontrollable...I dont think a prop change would help at all either....DJ

custom rc boat propellers (more speed)

[olwarbirds]

Manny, are you using a ball bearing to get your cup even ? ...Ive got so much to learn about props yet !!! ... DJ

[formulafastech]

Would a Prather 220 be a good prop for the impulse or a octura x440 fit I have these props already that's why I am asking I plan to use 4s 5s and maybe 6s if these props are no good can you tell me a good prop to use

[formulafastech]

Today while I was out driving my impulse I had no heat problems but other problems I was using 6s and it flipped the hatch came and the hatch seal came off to and I lost it cause it sank then the boat is supposed to be waterproof but my servo twitches now and my hatch has a crack I was mad when I lost the hatch seal and the servo twitches but other than that it ran fine but I was running in cool water too

[Hor2012]

Where r u in ny

[formulafastech]
